Title: Production of silicon nitride sintered compact
Inventor: HASE TEIZO
IPC: C04B35/58
Filed: 1991-10-29
Abstract: PURPOSE:To provide the silicon nitride sintered compact small in the mechanical strength drop at an elevated temperature. CONSTITUTION:A mixture of (A) 85-95wt.% of silicon nitride powder and (B) 5-15wt.% of sintering auxiliary powder comprising spinel (MgAl2O4) powder and zircon (ZrSiO4) powder is made into a form which is then sintered in a non-oxidative atmosphere at 1500-1700 deg.C to obtain the objective sintered compact. Based on the fact that a sintered compact made from the above zircon powder alone hardly varies in its mechanical strength in the temperature range from the room temperature to 1400 deg.C, the objective sintered compact is considered as being resistant to its mechanical strength drop even in the presence of the above-mentioned sintered compact as grain boundary phase after sintering.

Title: Photomask for fine pattern
Inventor: KADOWAKI AKIRA
IPC: G03F1/38
Filed: 1996-10-04
Abstract: PROBLEM TO BE SOLVED: To obtain a photomask for a fine pattern capable of shortening exposure time and easily attaining exposure at a very small width. SOLUTION: This photomask for a fine pattern consists of a glass substrate 1 formed with a photomask 2 and a resin substrate 4 fixed with glass fibers 3 fixed with the resin of the substrate 4 as an adhesive. Lots of the glass fibers 3 are formed in line and arranged just under the photomask 2.
